Further pure mathematics

This module covers important topics in the theory of pure mathematics including: number theory; the algebraic theory of rings and fields; and metric spaces. You will develop your understanding of group theory and real analysis and will see how some of these ideas are applied to cryptography and fractals. To successfully study this module you must have an interest in pure mathematics and ideally should already have studied pure mathematics at level 2 as provided by our level 2 module, Pure mathematics (M208).

What you will study

This module is based around six books with each one developing a particular topic in pure mathematics. A feature of the module is that we identify a core route through each book. This is designed to help time-poor students to identify material necessary to understand later parts of the module. It is possible to follow the core route for some weeks and the standard route for others. Following the core route through the whole module should enable you to pass but may not enable you to gain the higher grades.

Number Theory

In the first book we study the integers and prime numbers. In particular we look at classical problems that require integer solutions. For example finding all integer solutions to the equation 2x + 11y = 5. We also develop methods for solving linear congruences such as ax ≡ b (mod n) and in the final chapter we study the classical theorems of Fermat and Wilson.

Groups

In the second book we consolidate and build on the group theory presented at level 2 of our curriculum in Pure mathematics (M208). The book leads up to the classification of all finite abelian groups and ends with an introduction to the problem of classifying groups that are not abelian. On completion you will be able to use the Sylow Theorems to analyse the structure of appropriate finite groups.

Numbers and Rings

In the first half of this book we consider the solution of quadratic congruences, ax2 ≡ b (mod n). In the second half we use our knowledge of the integers to define and study the abstract algebraic structures known as rings.

Metric spaces I

In this book motivated by our understanding of how distance works for points in the plane, we define metrics, which can be used to give us an idea of distance between arbitrary objects (such as words or fractals). This allows to generalise the notion of what it means for a function to be continuous.

Rings and Fields

In this book we return to our study of algebra. We start by looking at polynomial rings and then continue our investigation of abstract algebraic structures. This unexpectedly leads to the resolution of some famous problems of antiquity such as ‘squaring the circle’ or ‘trisecting the angle’. The final chapter shows how algebraic ideas underlie the modern theory of cryptography.

Metric Spaces II

In this book we return to metric spaces. We look at the implications of our new definition of distance for understanding what it means for something to be connected. This book culminates in an introduction to the theory of fractals.

There is a non-assessed reader on the module website that provides an overview of the historical development of topological and metric spaces, and modern algebra. Where appropriate the reader includes information and/or links about modern applications and unsolved/recently solved problems.

Professional recognition

This module may help you to gain membership of the Institute of Mathematics and its Applications (IMA). For further information, see the IMA website.

Entry requirements

There is no formal pre-requisite study, but you must have the required mathematical skills.

You can check you’re ready for M303 and see the topics it covers here.

Talk to an advisor if you’re not sure you’re ready.

Preparatory work

You should aim to be confident and fluent with the concepts covered in the Are you ready? quiz here, and follow the advice in the quiz.

The key topics to revise include:

  • group theory
  • linear algebra
  • real analysis.

Pure mathematics (M208) is ideal preparation.

What's included

Six printed module books and a handbook (which can be taken into the examination). Informal online recorded lectures given by the module team. A study planner, history reader, module forums, assessment materials, practice quizzes and optional supplementary information available via the module website.

You will need

A calculator would be useful for the number theory-related parts of the module, though it is not essential. A simple four-function (+ – x ÷) model would suffice.

Computing requirements

A computing device with a browser and broadband internet access is required for this module. Any modern browser will be suitable for most computer activities. Functionality may be limited on mobile devices.

Any additional software will be provided, or is generally freely available. However, some activities may have more specific requirements. For this reason, you will need to be able to install and run additional software on a device that meets the requirements below.

A desktop or laptop computer with either an up-to-date version of Windows or macOS.

The screen of the device must have a resolution of at least 1024 pixels horizontally and 768 pixels vertically.

To join in the spoken conversation in our online rooms we recommend a headset (headphones or earphones with an integrated microphone).

Our Skills for OU study website has further information including computing skills for study, computer security, acquiring a computer and Microsoft software offers for students.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part. If you want to participate, you’ll likely need a headset with a microphone.

Assessment

The assessment details for this module can be found in the facts box above.

You can choose whether to submit your tutor-marked assignments (TMAs) on paper or online through the eTMA system. You may want to use the eTMA system for some of your assignments but submit on paper for others. This is entirely your choice.

Each of the six module books has an associated practice quiz on the module website. You can attempt these quizzes as many times as you wish and they do not count towards your final grade.

Each TMA is associated with a particular module book and consists of a mixture of questions: some of which contribute to your final grade, and some are developmental. The feedback you receive on your answers will help you to improve your knowledge and understanding of the study material and to develop important skills associated with the module.

If you have a disability

The OU strives to make all aspects of study accessible to everyone and this Accessibility Statement outlines what studying M303 involves. You should use this information to inform your study preparations and any discussions with us about how we can meet your needs.
